6 Claims.

The present invention relates generally to improvements in the art ofdispensing liquids, and relates more particularly to improvements in theconstruction of spray heads.

Generally defined, an object of our present invention is the provisionof an improved plumbing fixture which is simple in construction, neatand attractive in appearance, and highly efficient and practical in use.

10 As shown in co-pending application Serial No.

166,138, filed September 28, 1937, it has hereto- I fore been proposedto attach a'spray head to the end of a normally concealed hose for usein connection with kitchen sinks or the like; The spray head thereinshown, however, is not of the most practical construction since it ishighly desirable to provide a spray head of highly attractive appearanceand conveniently accessible so as to permit disposition in a retainingsocket 2o placed anywhereupon the sink without detracting therefrom andit is furthermore extremely desirable to provide a spray head which canbe safely used with either hot or cold water.

It is therefore a more specific object of our invention to provide aspray head of neat and attractive appearance and which is adapted foruse in connection with kitchen sink assemblages of the aforementionedtype.

A further specific object'of our invention is to provide an insulatedspray head which provides adequate protection to the user when hot wateris passed therethrough.

A still further object of our present invention is to provide a sprayhead adapted to cooperate with a flexible conduit and with a sink and ofsuch shape and construction as to be readily manipulated; Y

Still another specific object of the invention is to provide a sprayhead of durable construction which may be dropped or bumped against hardobjects without danger of breaking the nozzle or other objects.

An additional specific object of the present invention is to provide aspray head which may be manufactured at moderate cost and which maybereadily installed and operated.

Th e and other specific objects and advantages ill be apparent from thefollowing detailed decrlptio A clear onception of the several featurescoristituting our present improvement, and of the mode of constructingand of applying spray heads in accordancev with the invention, may behad by referring to the drawing accompanying and forming a part of thisspecification wherein the reference characters designate the same orsimilar parts in the various views.

Fig. 1 is a fragmentary part sectional front view of a sink showing theimproved spray head in normal position as applied to a kitchen sinkassemblage; I I

Fig. 2 is a transverse vertical section through the sink taken along theline 2-2 of Fig. 1 and showing the improved spray head in extendedposition;

' Fig. 3 is an enlarged fragmentary part sectional side elevation of theimproved spray head as appliedto a portion ofthe sink; and

Fig. 4 is a transverse horizontal section through the assemblage takenalong the line 4-4 of Fig. 3.

While the invention has been shown and described as being specificallyembodied in a special type of sink assemblage, it is not the intent tothereby unnecessarily restrict the scope, since the features are moregenerally applicable to plumbing fixtures.

Referring to the drawing, the sink assemblage shown in Figs. 1 and 2,comprises in general a sink having a basin 5 provided with a drain 6,drain boards 1, 8 for dishes or other objects formed integral with theopposite ends of the basin, a rear ,wall 9 formed integral with thebasin and HEISSUED' MAL 1. 3 194i drain boards, and an apron I0 alsoformed invalves l3, M respectively and an adjustable spout I I5 disposedbetween these valves l3, l4. Communicating with the lower portion of thespout I5 is a flexible hose or conduit it through which hot or coldwater may be diverted by manipula tion of a diverter valve control II.This flexible hose I6 is confined beneath the sink and is concealed bythe sink cabinet l8.

The present improved spray head 19, shown in detail in'Fig. 3, consistsof a hose attachment plug or fitting 20. having a hose retaining knob2|, a curved brass tube 22 secured at one end to the fitting 20 andhaving its opposite end provided with a spray nozzle 23. A rubbercovering 24 provides a convenient gripping handle above the nozzle andis either pre-molded and slipped over the tube 22 and around the spraynozzle '23, or it may be molded directly upon these elements. and theend of the covering 24 tected against damage by a snug fitting sleeve 25having a polygonal lower end. A tubular guide nut 26 having a polygonalhole is adapted to coact with the polygonal portion of the sleeve 25 toretain the spray head IS in any desired normal or inactive position, andis secured within a bore 21 in the elevated portion I I of the sink bymeans of a sleeve 28 coacting therewith, see Figs. 3 and 4.

The curved tube 22 may first be formed in the desired shape and sizewith one end thereof threaded or otherwise adapted to receive the hosefitting 20. The spray nozzle 23 of desired shape and size may then bethreaded or otherwise attached to the tube 22 at the end remote from thethreading and the rubber covering 24 may thereafter be applied to thetube 22 and nozzle 23.

The hose fitting 20 may then be attached to the threaded end of the tube22 and the sleeve 25 may thereafter be attached thereto around theadjacent end of the covering 24, thus completing the spray headassemblage. A hole 21 may then be bored in any desired and convenientlyaccessible part of the elevated portion ll of the sink, but it ispreferable to have this bore 21 to the left of the faucet l2 and nearthe drain board 8 as shown in Fig. 1 because in washing dishes, thedirty dishes are usually placed on the drain board I, are washed in thebasin 5, and are then placed on the drain board 8 for rinsing .which maybe conveniently done with the spray head and apparatus shown. The nut 26may then be placed within the bore-21 and the sleeve 28 may be screwedor otherwise attached thereto from the lower side of the sink portionll, thus firmly securing the nut 26 in position. The fiexible hose l6which communicates with the diverter, may then be pulled through thehole in the nut 26 and may thereafter be forced over the knob 2| of thefitting 20 until it tightly embraces the fitting.

From the foregoing description it will be ap-' parent that the presentinvention provides a simple spray head which is extremely neat inappearance, durable in construction, and highly eillcient in use. Thespray head may be formed in any desired shape or size and may bepositioned on any desired portion of the sink without detractingtherefrom. The rubber or similar covering provides a highly efficientinsulating shield serving as a protection to the user against burning,and furthermore as a protec tion against possible chipping of the sinkenamel and of dishes resting upon the sink. The improved spray head ismoreover attractive in appearance; and by virtue of the polygonal or lsquare formation of the sleeve 25 and of the hole in the nut 26, thenozzle or head [9 may be set in various fixed positions whennot beinghandled. Obviously, instead of using rubber, other resilient materialmay be employed, and

the covering 2| provides an enlarged conveniently accessible grippingportion above the nozzle and thus facilitates safe manipulation of thenozzle. The diverter valve and control I! provide simple means forby-passing the flow either to the spout l8 or to the spray head I9 atthe will of the operator. The improved spray head has proven highlysuccessful in actual commercial use, and can be convenientlymanufactured for sale at moderate cost.
